1. Use brute force during installation. Directly hitting the bearing with a hammer will cause the greatest damage to the imported bearing; it is the main cause of deformation.
2, the installation is not in place, the installation is biased or not installed in the imported bearing position, resulting in too small clearance of the imported bearings. The inner and outer rings are not in the center of uniform rotation, causing disagreement.
Recommendation: Select an appropriate or professional imported bearing installation tool, and use a special instrument to detect it after installation.
Second, poor lubrication (about 36%)
According to the survey, poor lubrication is one of the main causes of premature failure of imported bearings. The main reasons include: not adding lubricant or lubricating oil in time; lubricant or lubricating oil is not filled in place; improper selection of lubricant or lubricating oil; inaccurate lubrication method, etc.
Recommendation: Choose an accurate lubricant or lubricant and use an accurate lubrication method.
Third, pollution (about 14%)
Pollution can also lead to premature damage to imported bearings. Contamination means that dust, metal chips, etc. enter the inside of the imported bearings. The main reasons include: opening the imported bearing packaging too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the imported bearings is not clean, and the working medium is polluted.
Recommendation: It is best not to disassemble the packaging of the imported bearings before use; keep the installation environment clean during installation, clean the imported bearings to be used; and strengthen the sealing device of the imported bearings.
Fourth, tired (about 34%)
Tired damage is a common form of damage to imported bearings. Common causes of fatigue damage may be: long-term overload operation of imported bearings; failure to repair in time; improper maintenance; equipment aging.
Recommendation: Select the appropriate type of imported bearings and replace the worn bearings in time.
The above are the most common causes of early damage to imported bearings; the reasons for the early damage of imported bearings are various. The above are the main reasons for consideration, and sometimes it may be a comprehensive cause. If the imported bearing is selected accurately, the installation method is accurate, the lubrication method and lubricant selection are accurate, and the imported bearings can work normally for a long time.
